I'm trying build PyLucene off of Lucene's current trunk, on OS X
10.5.6.

So I first did "ant package-tgz" in a clean Lucene checkout, to get a
tgz with all interesting JARS (side note: it'd be nice if JCC could
get the JARs out of the tgz or zip file).

PyLucene's Makefile does all of that for you.
As described here:
  http://lucene.apache.org/pylucene/documentation/install.html

1. build JCC
2. use the Makefile to build PyLucene

Then I tried to run the example at
http://lucene.apache.org/pylucene/jcc/documentation/readme.html but
hit a few initial challenges:

* Where does extensions.jar come from?  (I'm trying to run jcc, and
  apparently I need to point it to extensions.jar).

PyLucene's Makefile builds it for you.

* I'm getting a cryptic error from JCC when it tries to init the
  JVM (I'm on OS X 10.5.6):

_NSJVMLoadLibrary: NSAddLibrary failed for 
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Libraries/libjvm.dylib
JavaVM FATAL: Failed to load the jvm library.

Could it be a 64-bit vs 32-bit VM issue. On Mac OS X, Python is 32-bit 
unless you build your own. Be sure to use the corresponding Java VM.

ValueError: An error occurred while creating Java VM

  I'm using 1.6.0 Java VM.  Maybe I'm supposed to use 1.5?
